Deep packet inspection virtual function

ABSTRACT

Concepts and technologies are disclosed herein for providing and using a deep packet inspection virtual function. A control system can detect a service request. The control system can analyze a policy to determine a function of a service to which the service request relates, a virtual machine that will host the function, and a deep packet inspection virtual function associated with the service. The control system can trigger loading of an image to the virtual machine and instantiation of the virtual machine. The image can include the function of the service and the deep packet inspection virtual function. The control system can validate the service and the deep packet inspection virtual function.

BACKGROUND

Service creation, maintenance, and delivery have evolved over the pastseveral years. One area that has changed services is the advent ofvirtualization. For example, the European Telecommunications StandardsInstitute (“ETSI”) network functions virtualization (“NFV”), softwaredefined networking (“SDN”), and other “cloud” computing architecturesand technologies have resulted in a change to the traditionalhardware-software model or paradigm. For example, services can becreated and deployed on commercial-off-the-shelf (“COTS”) hardware,which can allow flexibility in terms of scaling, locating, and/or usingthe services. Building services that were designed for deployment ondedicated infrastructure and instead deploying these same services in avirtualized infrastructure may not provide the benefits of using avirtualized network. Similarly, accommodating message routing betweenservice components used to provide a virtualized service may requireincreased complexity of the virtualized service relative to servicesbuilt on a dedicated infrastructure. Thus, while virtualization mayprovide flexibility to network operators and other entities, severalchallenges pose difficulties in migrating services to virtualizednetworks.

SUMMARY

The present disclosure is directed to a deep packet inspection virtualfunction. A computing device can host a control system, which caninclude multiple modules or applications that can be used to create,validate, and/or manage one or more deep packet inspection functions.The deep packet inspection function can be created as an application orservice (“service”) by the control system, as a component of theservice, and/or as an independent function or application that can bechained to one or more services. Thus, the control system can chain thedeep packet inspection function to other services or create the deeppacket inspection function as part of the services. The deep packetinspection function also can be created as a standalone application,service, or component. The deep packet inspection function can include adeep packet inspection virtual switch and a deep packet inspectionvirtual function. The deep packet inspection virtual function can becreated, modified, managed, and/or terminated by the service control andthe deep packet inspection virtual switch can be created, modified,managed, and/or terminated by the network control. Traffic can be routedto the deep packet inspection function from various sources such asservices, functions, or the like.

The control system can detect a request for a service or a request toconfigure or reconfigure a service. In some embodiments of creating orscaling services, the control system (or an operations managementcontroller of the control system) can analyze one or more policies todetermine how to create or scale the service. The control system canaccess a service creation database to identify one or more “recipes”that can be used to scale or create the service. The recipes can defineservice components including hardware, software, and/or transport aswell as deep packet inspection functions and/or components of the deeppacket inspection functions. The recipes also can define whether thedeep packet inspection functions are to be created or scaled as a partof a service and/or if the deep packet inspection function is to becreated or scaled as a standalone or independent deep packet inspectionfunction.

The control system can access an inventory of resources to determine ifresources needed to support the new service, the scaled service, and/orthe embedded or standalone deep packet inspection function areavailable. The control system can identify a service control functionthat is to control the scaled or created service and/or the deep packetinspection function and allocate or create the service control function.The control system can, via an infrastructure control, instantiate oneor more virtual machines and load and validate deep packet inspectionfunctions components (e.g., deep packet inspection virtual functionsand/or deep packet inspection virtual switches) and/or servicecomponents (e.g., virtual network functions and/or virtual servicefunctions and the like) to the virtual machines.

DETAILED DESCRIPTION

The following detailed description is directed to a deep packetinspection virtual function. A computing device can host a controlsystem, which can include multiple modules or applications that can beused to create, validate, and/or manage one or more deep packetinspection functions. The deep packet inspection function can be createdas an application or service (“service”) by the control system, as acomponent of the service, and/or as an independent function orapplication that can be chained to one or more services. Thus, thecontrol system can chain the deep packet inspection function to otherservices or create the deep packet inspection function as part of theservices. The deep packet inspection function also can be created as astandalone application, service, or component. The deep packetinspection function can include a deep packet inspection virtual switchand a deep packet inspection virtual function. The deep packetinspection virtual function can be created, modified, managed, and/orterminated by the service control and the deep packet inspection virtualswitch can be created, modified, managed, and/or terminated by thenetwork control. Traffic can be routed to the deep packet inspectionfunction from various sources such as services, functions, or the like.

The control system can detect a request for a service or a request toconfigure or reconfigure a service. In some embodiments of creating orscaling services, the control system (or an operations managementcontroller of the control system) can analyze one or more policies todetermine how to create or scale the service. The control system canaccess a service creation database to identify one or more “recipes”that can be used to scale or create the service. The recipes can defineservice components including hardware, software, and/or transport aswell as deep packet inspection functions and/or components of the deeppacket inspection functions. The recipes also can define whether thedeep packet inspection functions are to be created or scaled as a partof a service and/or if the deep packet inspection function is to becreated or scaled as a standalone or independent deep packet inspectionfunction.

The control system can access an inventory of resources to determine ifresources needed to support the new service, the scaled service, and/orthe embedded or standalone deep packet inspection function areavailable. The control system can identify a service control functionthat is to control the scaled or created service and/or the deep packetinspection function and allocate or create the service control function.The control system can, via an infrastructure control, instantiate oneor more virtual machines and load and validate deep packet inspectionfunctions components (e.g., deep packet inspection virtual functionsand/or deep packet inspection virtual switches) and/or servicecomponents (e.g., virtual network functions and/or virtual servicefunctions and the like) to the virtual machines.

According to various embodiments of the concepts and technologiesdescribed herein, the deep packet inspection function can be configuredby configuration data. The configuration data can define how traffic orother data will be inspected by the deep packet inspection function aswell as actions, if any, the deep packet inspection function should takewith respect to the traffic and/or data flows. According to variousembodiments, the deep packet inspection function can be configured byconfiguration data that can be obtained via one or more applicationprogramming interfaces (“APIs”). The configuration data can defineactions to take with respect to traffic including, but not limited to,blocking traffic, forking traffic to additional or alternativedestinations, reporting events to various devices, applying trafficshaping and/or quality of service (“QoS”) functions to the traffic,modifying contents of the traffic, combinations thereof, or the like.

According to various embodiments, the deep packet inspection virtualfunction of a deep packet inspection function can create softwaredefined networking (“SDN”) configuration data that can be routed to anetwork control component of the control system (either directly or viaa service control of the control system) by the deep packet inspectionfunction. The SDN configuration data can be used by the network controlto configure the deep packet inspection virtual switch. Thus, the deeppacket inspection function can be configured via configuration dataobtained via an API and/or can create configuration data that configuresthe deep packet inspection function.

While the subject matter described herein is presented in the generalcontext of program modules that execute in conjunction with theexecution of an operating system and application programs on a computersystem, those skilled in the art will recognize that otherimplementations may be performed in combination with other types ofprogram modules. Generally, program modules include routines, programs,components, data structures, and other types of structures that performparticular tasks or implement particular abstract data types. Moreover,those skilled in the art will appreciate that the subject matterdescribed herein may be practiced with other computer systemconfigurations, including hand-held devices, multiprocessor systems,microprocessor-based or programmable consumer electronics,minicomputers, mainframe computers, and the like.

Referring now to FIG. 1, aspects of an operating environment 100 forvarious embodiments of the concepts and technologies disclosed hereinfor a deep packet inspection virtual function will be described,according to an illustrative embodiment. The operating environment 100shown in FIG. 1 includes a computing device or system (hereinafterreferred to as a “control system”) 102. The control system 102 can hosta network control framework. The control system 102 can operate on, incommunication with, and/or as a part of a communications network(“network”) 104. Additional aspects of the network 104 are illustratedand described below with reference to FIG. 9. Briefly, it should beunderstood that the network 104 can include almost any type of computernetwork as well as communications networks.

According to various embodiments, the functionality of the controlsystem 102 may be provided by one or more server computers,workstations, desktop computers, laptop computers, other computingsystems, combinations thereof, or the like. In some embodiments, thefunctionality of the control system 102 can be provided by a distributedcomputing system that can host processing and/or storage resources thatcollectively can be configured to provide the functionality illustratedand described herein. Thus, it should be understood that thefunctionality of the control system 102 can be provided by a singledevice, by two or more similar devices, and/or by two or more dissimilardevices. For purposes of describing the concepts and technologiesdisclosed herein, the control system 102 is described herein asincluding a server computer. It should be understood that thisembodiment is illustrative, and should not be construed as beinglimiting in any way.

The control system 102 can execute an operating system (not shown inFIG. 1) and one or more application programs, modules, or othercomputer-executable instructions that, when executed by a processor (notshown in FIG. 1) of the control system 102 can provide the functionalityillustrated and described herein. The operating system can include acomputer program for controlling the operation of the device, and theapplication programs, modules, or other computer-executable instructionscan include executable programs configured to execute on top of theoperating system to provide various functions as illustrated anddescribed herein.

Although the control system 102 is illustrated and described in FIG. 1as including multiple modules, components, and/or other elements, itshould be understood that the functionality of these modules,components, and/or elements can be provided by application modulesexecuted by a single device, in some embodiments. In some otherembodiments, the functionality of the modules, components, and/orelements can be provided by multiple devices. As such, the illustratedand described embodiment should be understood as being illustrative ofone contemplated embodiment of the concepts and technologies describedherein and should not be construed as being limiting in any way.

As shown in FIG. 1, the control system 102 can include an operationsmanagement controller 106. The operations management controller 106 canbe configured to provide control and management of the control system102 and/or the various elements thereof. According to variousembodiments, the operations management controller 106 can provide highlevel and end-to-end control of services, creation of services, and/ormanagement of services, as well as creation, validation, and/ormanagement of deep packet inspection elements as will be illustrated anddescribed in further detail herein.

According to various embodiments of the concepts and technologiesdescribed herein, the operations management controller 106 can manageservices and/or deep packet inspection elements across multiple “scopes”or “domains.” As used herein, a scope, scope domain, and/or domain canbe used to refer to aspects of the concepts and technologies describedherein and can include, but are not necessarily limited to, aninfrastructure scope, a network scope, and a service or application(“service”) scope. The operations management controller 106 also cancontrol and orchestrate service creation and management; validation ofservices and/or service components; as well as creation, management, andvalidation of deep packet inspection functionality as will beillustrated and described herein.

The operations management controller 106 can serve as a master serviceorchestrator (“MSO”) for the control system 102. The operationsmanagement controller 106 can instantiate new services and/or deeppacket inspection functions based upon “recipes” that can be stored in aservice creation database 108 or elsewhere as illustrated and describedherein. The operations management controller 106 also can useinformation stored in the inventory 110 when creating new servicesand/or deep packet inspection functions. As will be explained in moredetail hereinbelow, services can include deep packet inspectionfunctionality, in some embodiments, while in some other embodiments thedeep packet inspection functionality can be embodied by standalone deeppacket inspection functions that can be chained to services, locatedbetween services, and/or that can operate independently of otherservices. The operations management controller 106 also can instantiatescope control domain entities (e.g., controllers for infrastructure,network resources, and/or service functions), as will be explained inmore detail below.

The operations management controller 106 can handle messages and/orexceptions that can be generated by the operations management controller106 and/or exceptions that may be passed to the operations managementcontroller 106 from the scope control domain (e.g., the controllers forthe infrastructure, network resources, and/or the service functions) aswill be illustrated and described below in more detail. In someembodiments, deep packet inspection functions can generate events and/orreports that can be routed to and/or handled by the operationsmanagement controller 106 or other entities, as will be illustrated anddescribed in more detail below.

The operations management controller 106 also can run one or more highlevel data collection, analytics, and event handling (“DCAE”) processesto analyze data or events relating to services, deep packet inspectionfunctions, and/or the various components for managing the services, deeppacket inspection functions, and/or their associated infrastructure,network, and service components. The operations management controller106 also can run a policy decision function using a high level set ofpolicies for service creation, control, and/or validation as well asdeep packet inspection function creation, control, validation, and thelike.

As mentioned above, the service creation database 108 can defineproducts and services using definitions of components of services suchas hardware, software, and/or transport that can be referred to hereinas “recipes” or “service recipes.” The recipes for services can defineone or more deep packet inspection functions or function components, insome embodiments, while in some other embodiments the deep packetinspection functions and/or components can have deep packet inspectionrecipes that can be stored in the service creation database 108. Therecipes can specify one or more components of a service and/or deeppacket inspection function as well as processes or operations forputting the service and/or deep packet inspection function componentstogether.

As such, it can be appreciated that the service and/or deep packetinspection function recipes may involve a service scope (e.g., a set ofservice or application functions), a network scope (e.g., a set ofnetwork functions and/or information indicating how network transport isto be established, maintained, and/or used), and an infrastructure scope(e.g., where on the network 104 or other hardware the network andservice functions are to be located). The recipes also can implicitly orexplicitly specify whether the various components of the service and/ordeep packet inspection function should be chained together or if thecomponents should operate independently of one another. It should beunderstood that the term “service” as used herein can include an“application.” Thus, it should be understood that the term “service” isnot used to limit the concepts and technologies described herein in anyway. The service creation database 108 can be used by a serviceprovider, by third parties, and/or by customers.

The inventory 110 can maintain or reflect up-to-date information aboutresource utilization. The information can include a total number ofresources, an amount of available resources, an amount of resources inuse, or the like. It should be understood that the “resources” caninclude infrastructure resources, network resources, and/or serviceresources. Thus, the inventory 110 can be used to understand whatresources (in terms of infrastructure, network, and/or service) exist,what resources are in use, and/or what resources are free or available.

According to various embodiments, the inventory 110 can reside entirelywithin a control domain (e.g., within a service domain, network domain,or infrastructure domain) or elsewhere. For example, in some embodimentsthe inventory 110 can reside and/or can be represented by an inventoryand/or data structure that is hosted by the control system 102, thenetwork 104, and/or elsewhere. Thus, in some embodiments the inventory110 can include data indicating or reflecting all inventory(infrastructure, network, and service) for the entire network 104 and/orthe elements in communication with the network 104. Thus, the inventory110 can provide end-to-end active view capability for active and/orinactive resources across all scopes of the control system 102.

In some other embodiments, the inventory 110 may be divided across thescope controllers (described in further detail below) so that eachcontroller can have a local inventory that relates to that controller'sscope. A controller for the infrastructure domain, for example, canmaintain an infrastructure inventory. Similarly, controllers for networkand service scopes can maintain scope-specific inventories. Even ifscope-specific inventories are provided, the inventory 110 still canprovide end-to-end viewing capability for a divided or distributedinventory embodiment, if desired. It should be understood that thisexample is illustrative and therefore should not be construed as beinglimiting in any way.

According to various embodiments, the operations management controller106 can communicate with one or more infrastructure control elements orcontrollers (collectively referred to herein as “infrastructurecontrol”) 112. The infrastructure control 112 can manage assets ofnetwork infrastructure (“infrastructure”) 114. Thus, the infrastructurecontrol 112 can interact with the infrastructure 114 to instantiatevirtual resources such as virtual machines and/or virtual storagedevices and/or to allocate hardware resources that will host variousservice and/or network functions as illustrated and described herein.According to some embodiments, however, the infrastructure control 112may not manage networking functions and/or service functions, as will beexplained in more detail below.

The infrastructure control 112 can include and/or can execute a policyengine using an infrastructure set of policies. The infrastructurecontrol 112 also can handle infrastructure scope exceptions, in someembodiments. The infrastructure control 112 can include functionalityfor managing and orchestrating the infrastructure 114; infrastructureEMFs, which may manage various fault, configuration, accounting,performance, and security (“FCAPS”) capabilities; an infrastructuredata, collection, analytics, and events (“DCAE”) process (labeled as“INF DCAE” in FIG. 1) that can provide information to the controllerand/or to the operations management controller 106; a policy decisionfunction with infrastructure scope policies; and/or an infrastructureinventory function (labeled “INF Inventory” in FIG. 1) that canrepresent infrastructure-scoped inventory and usage information orprovide this information to the inventory 110. It should be understoodthat this example is illustrative and therefore should not be construedas being limiting in any way.

The infrastructure control 112 can receive instructions and/or requestsfrom the operations management controller 106 or other entities via anoperations management application programming interface (“API”) 116. Asshown in FIG. 1, there can be multiple APIs 116 that can be called oraccessed by various elements of the control system 102 to support thefunctionality illustrated and described herein. Although the APIs 116are given the same reference numeral in the drawings, it should beunderstood that one or more (or each) of the APIs 116 can use differenttechnologies (e.g., formats and/or semantics) to support calls to thevarious elements and/or to support the communications illustrated anddescribed herein. According to some embodiments, the API 116 between theinfrastructure control 112 and the operations management controller 106can correspond to an operations management (“OM”) API 116, though thisis not necessarily the case.

Similarly, the infrastructure control 112 can communicate with a networkcontrol device or controller (hereinafter collectively referred to asthe “network control”) 118 via a software defined networking (“SDN”) API116. Thus, it can be appreciated that the infrastructure control 112 andthe network control 118 can support SDN and virtualization technologiessimultaneously. As will be explained in more detail below, the networkcontrol 118 can be configured to create and manage virtual networkingfunctions (“VNFs”) 120 within the infrastructure 114. In some instances,the infrastructure control 112 also can load VM images with embeddedVNFs 120 (e.g., a virtual switch) in addition to, or instead of, thenetwork control 118. The functionality of the network control 118 willbe described in more detail below. The infrastructure control 112 alsocan load deep packet inspection functions to the VMs and/or can includedeep packet inspection functionality in VM images that can be loaded tothe VMs. These and other aspects of creating deep packet inspectionfunctions will be explained in more detail below, particularly withreference to FIGS. 2-8.

The infrastructure control 112 also can communicate with theinfrastructure 114 via an API 116. Thus, the infrastructure control 112can interact with the infrastructure 114 to instantiate resources and/orallocate hardware to support various functions as illustrated anddescribed herein. In addition to supporting the VNFs 120, theinfrastructure 114 also can interact with a service control device orcontroller (hereinafter collectively referred to as the “servicecontrol”) 122 to receive instructions for instantiating one or morevirtual service functions (“VSFs”) 124 within the infrastructure 114 aswell as receive instructions for instantiating one or more deep packetinspection functions and/or deep packet inspection function componentsas will be illustrated and described in more detail below. A VSF 124 caninclude a virtualized application or application component, and can beused to create other services of various types including, but notlimited to, basic services, segmented services, and/or compositeservices as will be illustrated and described in more detail herein. Thefunctionality of the service control 122 and creation of various typesof services using the service control 122 will be described in moredetail below.

The operations management controller 106 also can communicate with thenetwork control 118. The network control 118 can be responsible formanagement, deployment, operation, and coordination of a transportnetwork for a particular service and/or deep packet inspection function.According to various embodiments, the transport network between one ormore components of a service and/or deep packet inspection functions canbe created by creating a group of one or more VNFs 120 within theinfrastructure 114. The transport network also can include physicalnetwork functions (“PNFs”) 126, which can be selected from an availableinventory of physical resources, configured, and/or controlled by thenetwork control 118.

The transport network can include various VNFs 120, PNFs 126, and/orother networking functions. The PNFs 126 can include, for example,European Telecommunications Standards Institute PNFs (“ETSI PNFs”). Insome embodiments, the transport network may include other types ofnetworking functions such as leaf switches, spine switches, or the like,while in some other embodiments, leaf switches and/or spine switches maybe considered part of the infrastructure 114. The VNFs 120 can includevirtualized network functions that can exist in the network scope. Thus,according to various embodiments, the VNFs 120 can include virtualswitches (“vSwitches”), virtualized routing functions and/or virtualrouters, a virtual tap, or the like. Because the transport network caninclude other types of functions, it should be understood that theseexamples are illustrative and therefore should not be construed as beinglimiting in any way.

The network control 118 also can establish and manage software definednetworks, maintain a network scope resource inventory, run a networkscope data collection and analysis process, run a policy engine using anetwork scope set of policies, and handle network scope exceptions. Thenetwork control 118 can include a software defined network controller;one or more virtual network function management functions; one or morenetwork element management functions, which can manage FCAPS for networkscoped services; a network DCAE process (labeled as “NW DCAE” in FIG.1), which can provide information to the network control 118 and/or theoperations management controller 106; a network policy engine withnetwork scope policies; and a network inventory function (labeled as “NWInventory” in FIG. 1), which can provide network scoped inventory andusage information to the inventory 110.

According to various embodiments, the network control 118 can receiverequests from the operations management controller 106 via an API 116such as the OM API 116 discussed above. The requests from the operationsmanagement controller 106 received via the OM API 116 can instruct thenetwork control 118 to create, modify, and/or terminate one or morenetworking functions such as VNFs 120, PNFs 126, and/or someinfrastructure networking functions, if controlled or controllable bythe network control 118. The network control 118 also can be instructedby the service control 122 and/or the operations management controller106 to create, modify, and/or terminate one or more deep packetinspection components such as a deep packet inspection virtual switch(not shown in FIG. 1). The creation, configuration, and validation ofthe deep packet inspection virtual switch will be illustrated anddescribed in more detail below, particularly with reference to FIGS.2-8. These infrastructure networking functions can include networkhardware (e.g., switches, leaf switches and spine switches, or the like)and other infrastructure networking functions. Some other infrastructurenetworking functions (e.g., wires, physical ports, switches, leafswitches and spine switches (if not controlled by network control 118),or the like, can be considered a part of the infrastructure 114. Thenetwork control 118 also can be configured to receive instructions toestablish or modify transport using VNFs 120 and/or PNFs 126 in additionto, or instead of, instantiating the VNFs 120 and/or the PNFs 126. Itshould be understood that this example is illustrative and thereforeshould not be construed as being limiting in any way.

The network control 118 also can initiate requests to the infrastructurecontrol 112 via the OM API 116 to request and/or obtain additionalnetwork resources. For example, the network control 118 can request theinfrastructure control 112 to allocate one or more virtual machines(“VMs”) and load an image with an embedded VNF 120 to the VM. Thenetwork control 118 also can receive requests via an SDN API 116 frominfrastructure control 112 to create, modify, and/or terminatetransport. Thus, it can be appreciated that the network control 118 cansupport SDN and virtualization technologies simultaneously. It should beunderstood that this example is illustrative and therefore should not beconstrued as being limiting in any way.

The operations management controller 106 also can communicate with theservice control 122. The service control 122 can be responsible formanagement, deployment, operation, and coordination of services.Services can be provided by and/or can include one or more VSFs 124,non-virtualized service functions (“NVSFs”) 128, one or more EMFs 130,one or more VSF management functions (labeled “VSFMFs” in FIG. 1) 132,combinations thereof, or the like.

According to various embodiments, the services, service components, deeppacket inspection functions, and/or deep packet inspection functioncomponents can be created by the service control 122 by creating a groupof one or more VSFs 124, NVSFs 128, and/or deep packet inspectionvirtual functions (not shown in FIG. 1) within the infrastructure 114.Thus, it should be understood that the NVSFs 128 can be created and/orcontrolled by the service control 122. It also should be understood thatthe operations management controller 106 can create or prompt creationof the VSFs 124 and initiate requests to the infrastructure 114 andnetwork control 118. As such, it should be understood that theoperations management controller 106 and/or the service control 122 cancreate a service, and/or a deep packet inspection virtual function,depending upon a degree of delegation awarded to the service control 122by the operations management controller 106 when the operationsmanagement controller 106 created the service control 122.

According to various embodiments, the service control 122 also canmaintain a service scope resource inventory (labeled “Ser Inventory” inFIG. 1). The service scope resource inventory can be maintained at theservice control 122, in some embodiments, and can provide service scoperesource inventory and usage information to the inventory 110. Theservice control 122 can also run a service scope DCAE (labeled as “SerDCAE” in FIG. 1) to analyze messages and/or events occurring within orrelating to services, service components, and/or service functions suchas the VSFs 124 and the NVSFs 128.

The service control 122 also can run a policy engine for a service scopeset of policies. Thus, service-specific policies can be applied and/orused by the service control 122 when creating services, servicecomponents, and/or service functions such as the VSFs 124 and/or theNVSFs 128; as well as deep packet inspection functions and/or deeppacket inspection function components as will be illustrated anddescribed in more detail below with reference to FIG. 2. The servicecontrol 122 also can handle service scope exceptions, in someembodiments. As noted above, the operations management controller 106also can create services, service components, service functions, deeppacket inspection functions, and/or deep packet inspection functioncomponents depending upon the degree to which the operations managementcontroller 106 delegates control to the service control 122. It shouldbe understood that these example components of the service control 122are illustrative and therefore should not be construed as being limitingin any way.

The service control 122 can be responsible for management and control ofservices, components or functions of the services, deep packetinspection functions, and/or components of the deep packet inspectionfunctions. According to various embodiments, the service control 122 canmanage VSFs 124 and/or NVSFs 128 of services being controlled as well ascomponents of the deep packet inspection functions illustrated anddescribed herein. The service control 122 also can handle service EMFs,which can manage FCAPS for services being controlled. The service DCAEprocess can provide information to the service control 122 and/or theoperations management controller 106. The service control 122 also caninclude a service policy engine, which can apply and/or enforce servicescope policies. The service inventory can provide service scopeinventory and/or usage information to the inventory 110.

According to various embodiments, the service control 122 can receiverequests from the operations management controller 106 via an API 116such as the OM API 116 discussed above. The requests from the operationsmanagement controller 106 received via the OM API 116 can instruct theservice control 122 to create, modify, and/or terminate one or moreservice functions such as VSFs 124, the NVSFs 128, and the like, as wellas to create, modify, and/or terminate one or more deep packetinspection functions and/or deep packet inspection function components.It should be understood that this example is illustrative and thereforeshould not be construed as being limiting in any way.

The service control 122 also can initiate requests to the infrastructurecontrol 112 via the OM API 116 to request and/or obtain additionalinfrastructure resources and/or other resources. The service control 122also can initiate requests via an SDN API 116 to the network control118. Thus, it can be appreciated that the service control 122 cansupport SDN and virtualization technologies simultaneously. Theserequests can be configured to request creation, modification, and/ortermination of service-related transport and/or deep packet inspectionfunction transport (e.g., transport between service functions, servicecontrol functions, deep packet inspection functions, and/or deep packetinspection function components). It should be understood that thisexample is illustrative and therefore should not be construed as beinglimiting in any way.

The APIs 116 illustrated and described herein can include two or moretypes of APIs 116. In some embodiments, as mentioned above, the APIs 116can include an OM API 116 and/or SDN APIs 116. The APIs 116 can beexposed by some or all of the components within the control system 102.The APIs 116 can be exposed by the components to each other, for variouspurposes. For example, the APIs 116 can include an operations managementAPI 116, which can be exposed by the operations management controller106; infrastructure APIs 116, which can be exposed by the infrastructurecontrol 112; network APIs 116, which can be exposed by the networkcontrol 118; and service APIs 116, which can be exposed by the servicecontrol 122. Thus, it can be appreciated that the control system 102 andthe components thereof can support SDN and virtualization technologiessimultaneously.

The APIs 116 can be used to enable operational management within thecontrol system 102 and between the control system 102 and theinfrastructure 114. The APIs 116 can be exposed in either direction. Assuch, the APIs 116 can be exposed in a southbound direction, e.g., fromthe operations management controller 106 to the infrastructure control112, the network control 118, or the service control 122; from theinfrastructure control 112 to the infrastructure 114; from the networkcontrol 118 to the VNFs 120 loaded to the infrastructure 114; and/orfrom the service control 122 to the VSFs 124 loaded to theinfrastructure 114. The APIs 116 also can enable communications in anorthbound direction, e.g., the APIs 116 can enable the VNFs 120 toaccess the network control 118; the VSFs 124 to access or communicatewith the service control 122; and the infrastructure 114 to access theinfrastructure control 112. Similarly, the APIs 116 can be accessed bythe infrastructure control 112, the network control 118, and/or theservice control 122 to enable access to the operations managementcontroller 106. It should be understood that this example isillustrative and therefore should not be construed as being limiting inany way.

The SDN APIs 116 can be exposed by the network control 118 to theoperations management controller 106, the infrastructure control 112,and the service control 122. The SDN APIs 116 can enable the operationsmanagement controller 106, the infrastructure control 112, and theservice control 122 to make requests to the network control 118 for SDNservices. It should be understood that this example is illustrative andtherefore should not be construed as being limiting in any way.

By creating, allocating, and/or instantiating the VNFs 120, the PNFs126, the VSFs 124 the NVSFs 128, the EMFs 130, the VSF managementfunctions 132, and/or combinations thereof, the control system 102 cancreate a service 134 on the infrastructure 114. It should be understoodthat this example is illustrative and therefore should not be construedas being limiting in any way.

According to various embodiments, the control system 102 can integratean enhanced control, orchestration, management, and policy framework(hereinafter referred to as “ECOMP”) 136, which can be integrated intothe control system 102. The ECOMP 136 can enable rapid service creationby combining pre-built components and/or functions. The ECOMP 136 alsocan enable dynamically elastic capacity management by enabling scalingand instantiation. The ECOMP 136 also can support control functions. Thecontrol functions can be driven by real-time analytics and policydecisions.

The ECOMP 136 also can support unified operations, administration, andmanagement across the three scopes (e.g., infrastructure, network, andservice). The ECOMP 136 also can support optimization of deep packetinspection functions and/or services 134 and/or the components of thedeep packet inspection functions and/or services 134, analytics of thedeep packet inspection functions and/or the services 134, componentsthereof, and/or the various components of the control system 102. Asillustrated and described in the FIGURES, the ECOMP 136 can be anelement of the control system 102, in some embodiments, while in otherembodiments the control system 102 can correspond to an embodiment ofthe ECOMP 136. It should be understood that these examples areillustrative and therefore should not be construed as being limiting inany way.

The ECOMP 136 can include a service design and creation (“SDC”)environment, an active and available inventory (“AAI”), an operationsmanagement framework (“OMF”), and/or a service, infrastructure, and/ornetwork control. Thus, the ECOMP 136 can include, in some embodiments,the service creation database 108, the inventory 110, the operationsmanagement controller 106, and/or one or more of the infrastructurecontrol 112, the network control 118, and/or the service control 122. Itshould be understood that this example is illustrative and thereforeshould not be construed as being limiting in any way.

The SDC component of the ECOMP 136 can enable developers, servicedesigners, network planners/engineers, operations planners and productmanagers, other entities, or the like, to create, organize, prototype,and deploy services 134. In some embodiments, service definitions can beinstantiated by the OMF and the resulting service instances can berecorded in the AAI. According to various embodiments, componentsassociated with a service 134 can be created in the SDC component andstored as recipes. Thus, the SDC component can store recipes for VSFcomponents, VSFs 124, service components, deep packet inspectionfunctions, deep packet inspection function components, and variousnetwork and/or infrastructure resources. The recipes also can indicatewhether or not various components of the deep packet inspectionfunctions and/or the services 134 are to be chained together or are tooperate independently of one another. It should be understood that thisexample is illustrative and therefore should not be construed as beinglimiting in any way.

The AAI can provide real-time views of services, infrastructure, andnetworks in aggregate. The AAI can obtain the data from the servicecontrol 122 and the network control 118, and/or can supplement viewswith customer and account data. The OMF can provide and extend uponFCAPS capabilities through the use of analytics, policy, orchestration,and control functions. The OMF can be a repeating pattern of control,orchestration, DCAE, and policy management functions. It should beunderstood that this example is illustrative and therefore should not beconstrued as being limiting in any way.

In some embodiments, the OMF and service, infrastructure, and networkcontrol functions can form a series of closed loop control capabilities.These capabilities can be referred to as “operational control loops.”These “operational control loops” can be based on data and eventscollected and analyzed via the DCAE. Responsive actions can be basedupon policy, and may be taken by one or more of orchestration orcontroller functions. “Operational control loops” can be repeatingpatterns that may be implemented in various locations and supportingvarious scopes of operation.

In some embodiments, the OMF can interact with one or more businesssupport system (“BSS”) 138 and one or more operations support system(“OSS”) 140. The BSS 138 and the OSS 140 can be external to the ECOMP136, in some embodiments. The BSS 138 and the OSS 140 can interact withcustomers and operations in support of activities and aggregatecapabilities across services within and outside of the operatingenvironment 100.

Each instantiation of the OMF can be specifically tailored to the scopein which the OMF operates. The OMF may exist as a top-level end-to-endfunction that can be separate from service, infrastructure, and networkcontrol, and the platform components of the OMF may exist in variousplaces within service and network control. It should be understood thatthis example is illustrative and therefore should not be construed asbeing limiting in any way.

As mentioned above, although the operations management controller 106,the service creation database 108, the inventory 110, the infrastructurecontrol 112, the network control 118, the service control 122, and theECOMP 136 are illustrated as components of the control system 102, itshould be understood that each of these components, or combinationsthereof, may be embodied as or in stand-alone devices or componentsthereof operating as part of or in communication with the network 104and/or the control system 102. Thus, for example one or more of thesecomponents can be hosted by a server computer or other computing devicethat can access other devices via one or more of the APIs 116, and/orcan be accessed via one or more of the APIs 116. As such, theillustrated embodiment should be understood as being illustrative ofonly some contemplated embodiments and should not be construed as beinglimiting in any way.

As shown in FIG. 1, the control system 102 also can be used to create,validate, and/or manage one or more deep packet inspection functions142. The deep packet inspection function 142 can be created as a service134 by the control system 102, as a component of the service 134, and/oras an independent function or application as illustrated and describedherein. The control system 102 can be configured to chain the deeppacket inspection function 142 to other services 134, in someembodiments, or to create the deep packet inspection function 142 aspart of a service 134. In various embodiments, the deep packetinspection function 142 can be created as a standalone application,service, or component that can provide the functionality illustrated anddescribed herein for providing deep packet inspection in a virtualizedenvironment.

The components of the deep packet inspection function 142 will beillustrated and described in more detail herein, particularly withreference to FIG. 2. Briefly, however, the deep packet inspectionfunction 142 can include a deep packet inspection virtual switch and adeep packet inspection virtual function. According to variousembodiments, the deep packet inspection virtual function can be created,modified, managed, and/or terminated by the service control 122 and thedeep packet inspection virtual switch can be created, modified, managed,and/or terminated by the network control 118 and/or by the servicecontrol 122 via the network control 118. The configuration of these andother components of the deep packet inspection function 142 will beillustrated and described in more detail below.

According to various embodiments of the concepts and technologiesdescribed herein, the deep packet inspection function 142 can operateindependently. Thus, traffic can be routed to the deep packet inspectionfunction 142 from various sources such as the service 134, otherservices, or the like. In some other embodiments, the deep packetinspection function 142 can be created as a component of the service 134and as such, the functionality of the deep packet inspection function142 can be embedded within the service 134. In yet other embodiments,the deep packet inspection function 142 can be located between multipleservices 134. These and other embodiments will be illustrated anddescribed in more detail below.

In practice, the operations management controller 106 can detect arequest for a service 134. According to various embodiments, theoperations management controller 106 can detect a request to configureor reconfigure a service 134 or a request for a new service 134. In someembodiments of creating or scaling services 134, the operationsmanagement controller 106 can analyze one or more policies to determinehow the scaling or creation of the service 134 should be handled. Theoperations management controller 106 also can access the servicecreation database 108 to identify one or more “recipes” that can be usedto scale or create the service 134. The recipes can define servicecomponents including hardware, software, and/or transport as well asdeep packet inspection functions 142 and/or components of the deeppacket inspection functions 142. The recipes also can define whether thedeep packet inspection functions 142 are to be created or scaled as apart of a service 134 and/or if the deep packet inspection function 142is to be created or scaled as a standalone or independent deep packetinspection function 142.

The operations management controller 106 can access the inventory 110 todetermine if the resources needed to support the new service 134, thescaled service 134, and/or the embedded or standalone deep packetinspection function 142 are available for use. The operations managementcontroller 106 also can identify a service control function that is tocontrol the scaled or created service 134 and allocate or create theservice control function. Thus, the operations management controller 106can select, allocate, and/or create the service control function that isto control the service 134 and/or the deep packet inspection function142.

The operations management controller 106 can instruct the infrastructurecontrol 112 to instantiate one or more VMs and to load and validate deeppacket inspection functions components (e.g., deep packet inspectionvirtual functions and/or deep packet inspection virtual switches); VNFs120; and/or VSFs 124 to the VMs. It should be understood that if theservice 134 and/or deep packet inspection functions 142 are beingscaled, that the infrastructure control 112 may de-allocate deep packetinspection virtual functions, deep packet inspection virtual switches,VMs, VNFs 120, and/or VSFs 124 instead of instantiating the deep packetinspection virtual functions, deep packet inspection virtual switches,VMs, VNFs 120, and/or VSFs 124. The infrastructure control 112 can alsoinstruct the network control 118 to create or establish transportbetween the components of the deep packet inspection function 142 and/orthe VMs, the VNFs 120, the VSFs 124, and/or the service control 122. Inthe case of scaled down services 134, it can be appreciated that thenetwork control may de-allocate or tear down transport. The networkcontrol 118 can report events to the network DCAE and/or update thenetwork inventory (and/or the inventory 110).

The service control 122 can receive instructions from the operationsmanagement controller 106 to instantiate or tear down one or more deeppacket inspection virtual functions, in some embodiments. The servicecontrol 122 can report an event to a service DCAE and update the serviceinventory (and/or the inventory 110). The network control 118 also canreceive instructions to establish transport between the new deep packetinspection virtual functions and/or the VSFs 124 and report events tothe network DCAE for scaled up services 134 and/or can tear down networktransport supporting deep packet inspection virtual functions and/or theVSFs 124 and report events to the network DCAE for scaled down services134. The network control 118 can establish transport using VNFs 120and/or PNFs 126. The operations management controller 106 can validatethe deep packet inspection function 142 and/or the service 134end-to-end and/or update the inventory 110.

According to various embodiments of the concepts and technologiesdescribed herein, the deep packet inspection function 142 can beconfigured by configuration data. The configuration data can define howtraffic or other data will be inspected by the deep packet inspectionfunction 142 as well as actions, if any, to take with respect to thetraffic and/or data flows. According to various embodiments, the deeppacket inspection function 142 can be configured by configuration datathat can be obtained via one or more APIs. The configuration data candefine actions to take with respect to traffic including, but notlimited to, blocking traffic, forking traffic to additional oralternative destinations, reporting events to various devices, applyingtraffic shaping and/or QoS functions to the traffic, modifying contentsof the traffic, combinations thereof, or the like.

According to various embodiments, the deep packet inspection virtualfunction of a deep packet inspection function 142 can create SDNconfiguration data that can be routed to the network control 118 (eitherdirectly or via the service control 122) by the deep packet inspectionfunction 142. The SDN configuration data can be used by the networkcontrol 118 to configure the deep packet inspection virtual switch, aswill be illustrated and described in more detail below with reference toFIG. 2. Thus, the deep packet inspection function 142 can be configuredvia configuration data obtained via an API and/or can createconfiguration data that configures the deep packet inspection function142. These and other aspects of the deep packet inspection functions 142will be illustrated and described in more detail below.

FIG. 1 illustrates one control system 102, one network 104, oneoperations management controller 106, one service creation database 108,one inventory 110, one infrastructure control 112, one instance ofinfrastructure 114, one network control 118, one service control 122,one service 134, one ECOMP 136, one BSS 138, one OSS 140, and one deeppacket inspection function 142. It should be understood, however, thatvarious implementations of the operating environment 100 can includezero, one, or more than one control system 102; zero, one, or more thanone network 104; zero, one, or more than one operations managementcontroller 106; zero, one, or more than one service creation database108; zero, one, or more than one inventory 110; zero, one, or more thanone infrastructure control 112; zero, one, or more than one instance ofinfrastructure 114; zero, one, or more than one network control 118;zero, one, or more than one service control 122; zero, one, or more thanone service 134; zero, one, or more than one ECOMP 136; zero, one, ormore than one BSS 138; zero, one, or more than one OSS 140; and/or zero,one, or more than one deep packet inspection functions 142. As such, theillustrated embodiment should be understood as being illustrative, andshould not be construed as being limiting in any way.

Turning now to FIG. 2, additional aspects of the deep packet inspectionfunction 142 are illustrated and described in detail. In particular,FIG. 2 shows the deep packet inspection function 142 operating on theinfrastructure 114. According to some embodiments, as shown in FIG. 2,the deep packet inspection function 142 can be hosted and/or executed bya computer system 200. Although multiple services 134A-N (hereinaftercollectively and/or generically referred to as “services 134”) are shownas being executed and/or hosted by the same infrastructure 114 thathosts or includes the computer system 200, this is not necessarily thecase. In particular, the services 134 and/or the deep packet inspectionfunctions 142 can be hosted and/or executed by different devices and/orinfrastructure 114 in various embodiments. As such, the illustratedembodiment should be understood as being illustrative and thereforeshould not be construed as being limiting in any way.

The deep packet inspection function 142 can include multiple components,in some embodiments, as explained above and as shown. In particular, thedeep packet inspection function 142 can include a deep packet inspectionvirtual switch (labeled “DPI vSwitch” in FIG. 2) 202 and a deep packetinspection virtual function (labeled “DPI VF” in FIG. 2) 204. The deeppacket inspection function 142 also can be configured by way of the deeppacket inspection configuration data 206, as mentioned above. The deeppacket inspection virtual switch 202, the deep packet inspection virtualfunction 204, and the deep packet inspection configuration data 206 willbe described in additional detail below, as will other elements shown inFIG. 2.

As mentioned above, the deep packet inspection virtual switch 202 can becreated and/or controlled by one or more network control functions,which can be included in the network control 118 illustrated anddescribed above with reference to FIG. 1. The deep packet inspectionvirtual switch 202 can perform inspection and action at the transportlayer. Thus, the deep packet inspection virtual switch 202 can blocktraffic or other data flows. The deep packet inspection virtual switch202 also can be configured to route or fork the traffic and/or packetsthereof based upon one or more routing tables 208, which can be providedto the deep packet inspection virtual switch 202 by a network controlfunction of the network control 118. It can be appreciated from theabove description of the control system 102 that the deep packetinspection virtual switch 202 can be instantiated by the operationsmanagement controller 106 or other entities, according to variousembodiments.

According to various embodiments of the concepts and technologiesdescribed herein, the deep packet inspection virtual switch 202 can beconfigured by SDN configuration data 210. The SDN configuration data 210can be forwarded to the deep packet inspection virtual switch 202 by thenetwork control 118. In some embodiments, the SDN configuration data 210can be generated by the deep packet inspection virtual function 204, aswill be explained below, and routed to the network control 118 by thedeep packet inspection virtual function 204 directly and/or via theservice control 122, as shown in FIG. 2. Thus, the deep packetinspection virtual function 204 can tailor functionality of the deeppacket inspection virtual switch 202 via the SDN configuration data 210in some embodiments. It should be understood that this example isillustrative and therefore should not be construed as being limiting inany way.

The deep packet inspection virtual function 204 can provide inspection,analysis, and action at the application or service layer for trafficthat arrives at the deep packet inspection function 142. Actions thatcan be taken by the deep packet inspection virtual function 204 withrespect to the traffic can include, but are not limited to, storingpackets for analysis, modifying content of the packets, creating anddistributing reports or events relating to the traffic, or the like.

As mentioned above, the deep packet inspection virtual function 204 alsocan be configured to generate the SDN configuration data 210. The deeppacket inspection virtual function 204 therefore can instruct a networkcontrol function of the network control 118 to configure the deep packetinspection virtual switch 202 by way of the SDN configuration data 210.Thus, the deep packet inspection virtual function 204 can instruct thenetwork control function to configure the deep packet inspection virtualswitch 202 to route or fork packets. In some embodiments, the deeppacket inspection virtual function 204 can provide the SDN configurationdata 210 directly to the network control 118 while in some otherembodiments, the deep packet inspection virtual function 204 can providethe SDN configuration data 210 to the service control 122 for routing tothe network control 118. Both embodiments are shown in FIG. 2.

Thus, the deep packet inspection configuration data 206 can be used todefine how the deep packet inspection function 142 will inspect trafficor other data at the deep packet inspection function 142. The deeppacket inspection configuration data 206 can include instructions thatcan describe what packets will be inspected by the deep packetinspection function 142, what actions will be taken with respect to thetraffic, whether or not reports or events are to be generated by thedeep packet inspection function 142, combinations thereof, or the like.The deep packet inspection configuration data 206 can be provided to thedeep packet inspection function 142 via an application programminginterface (“API”) exposed by the deep packet inspection virtual function204, a system that executes or hosts the deep packet inspection function142, other devices, combinations thereof, or the like. In someembodiments, the deep packet inspection configuration data 206 can bereceived via a deep packet inspection application programming interface(not shown in FIG. 2) and therefore can be configured remotely. Itshould be understood that this example is illustrative and thereforeshould not be construed as being limiting in any way.

Thus, it can be appreciated that the deep packet inspection function 142can be configured to inspect traffic or other data flows that flow intothe deep packet inspection function 142. According to variousembodiments of the concepts and technologies described herein, the deeppacket inspection function 142 can inspect the traffic based upon a setof configuration data, illustrated and described herein as deep packetinspection configuration data 206. The deep packet inspection function142 can perform actions based upon the deep packet inspectionconfiguration data 206. In particular, then actions can include, but arenot limited to, blocking the traffic, forking the traffic to one or morelocations, reporting an event to one or more devices, applying qualityof service and/or traffic shaping functions to the traffic, modifyingcontents of the traffic (e.g., headers, payload, or both), combinationsthereof, or the like.

As shown in FIG. 2, the deep packet inspection function 142 and/or theinfrastructure 114 that hosts the deep packet inspection function 142can be hosted or executed by the computer system 200. The computersystem 200 can include a memory 212 and a processor 214. The computersystem 200 can, via execution of computer-executable instructions storedin the memory 212 by the processor 214, provide the functionalityillustrated and described herein with reference to the deep packetinspection function 142. Various methods or processes associated withthe deep packet inspection function 142 are illustrated and describedherein, particularly with reference to FIGS. 4-8. An examplearchitecture of the computer system 200 is illustrated and describedherein with reference to FIG. 10. It should be understood that theseexamples are illustrative and therefore should not be construed as beinglimiting in any way.

As shown in FIG. 3, the deep packet inspection function 142 can bedeployed as a standalone service, application, module, or entity insteadof, or in addition to, being deployed as an embedded function withinother services 134. In some embodiments, the deep packet inspectionfunction 142 can be integrated and/or tightly coupled to one or moreservices 134, e.g., the deep packet inspection function 142 can be fullyintegrated into an existing VF or can be created as a separate VF thatcan be tightly coupled to other VFs of a service 134.

In some other embodiments, as illustrated and described herein, the deeppacket inspection function 142 can be created as a standalone VF thatcan be chained to one or more services 134 on demand (e.g., when aparent orders parental controls, when a service provider enablesfiltering, for enabling probes, etc.). As used herein, a “tightlycoupled” deep packet inspection function 142 may be highly integratedwith service 134 to which the deep packet inspection function 142 istightly coupled but cannot be reused for other services 134, while astandalone deep packet inspection function 142 may not be integral to aservice 134 but can be chained to a service 134 and reused for otherservices 134.

According to various embodiments, the deep packet inspection function142 illustrated and described herein is a standalone function. Thus, thedeep packet inspection function 142 has its own service control functionand can be chained to other services 134 by the MSO, if desired.According to various embodiments, the deep packet inspection function142 can be chained to services 134 by inserting the deep packetinspection function 142 between an (N−1)th service 134(N−1) and an Nthservice 134N. According to various embodiments, the operationsmanagement controller 106 (which can include functionality associatedwith an MSO in various embodiments) can insert the deep packetinspection function 142 between the two or more services using an SDNcontrolled switch such as the deep packet inspection virtual switch 202.

The deep packet inspection configuration data 206 can be provided to thedeep packet inspection virtual function 204 through an applicationprogramming interface from a virtual function that may not be a part ofa service 134 (or services 134) to which the deep packet inspectionfunction 142 is chained. In some embodiments, the deep packet inspectionconfiguration data 206 can be provided to the deep packet inspectionvirtual function 204 via one or more virtual functions of the services134 to which the deep packet inspection function 142 is chained. Itshould be understood that this example is illustrative and thereforeshould not be construed as being limiting in any way.

In one embodiment of the concepts and technologies described herein, thedeep packet inspection function 142 can be placed between the EPC andthe IMS for the purpose of inspecting SIP messages. Thus, the services134 in this example are the EPC and the IMS. The deep packet inspectionconfiguration data 206 can be provided by a virtual network functionand/or by the IMS. It should be understood that this example isillustrative and therefore should not be construed as being limiting inany way.

In another embodiment of the concepts and technologies described herein,the deep packet inspection function 142 can be placed at an egress pointof the EPC. The deep packet inspection function 142 can be configured toinspect user data such as search strings, or the like. The deep packetinspection function 142 can be separate from the EPC and/or can bechained to the EPC. The deep packet inspection configuration data 206can originate from a virtual network function that is not a part of theEPC. It should be understood that the deep packet inspection function142 can be chained to a single service 134 as in this example (where thedeep packet inspection function 142 is chained to an exit point of thenetwork 104) though there may be another service 134 to which forkedtraffic and/or events are routed. It should be understood that theseexamples are illustrative and therefore should not be construed as beinglimiting in any way.

Turning now to FIG. 3, additional aspects of a deep packet inspectionfunction 142 are illustrated and described in detail. In particular,FIG. 3 illustrates various traffic patterns that can be supported by thedeep packet inspection function 142, according to various embodiments ofthe concepts and technologies described herein. As illustrated anddescribed above with reference to FIG. 2, the deep packet inspectionfunction 142 can be located in proximity to one service 134, inproximity to two or more services 134, in proximity to or within atraffic flow path that leads to one service 134, in proximity to orwithin a traffic flow path that leads from one service 134, in proximityto or within a traffic flow path that leads to two or more services 134,and/or in proximity to or within a traffic flow path between two or moreservices 134. As such, it should be understood that this example isillustrative and therefore should not be construed as being limiting inany way.

As shown in FIG. 3, traffic 300 can arrive at the deep packet inspectionfunction 142 via an inbound traffic path 302, which can correspond to apath along which traffic flows to the deep packet inspection function142. The inbound traffic 300 can correspond to a data flow, a trafficflow, and/or other strings or sets of data packets 304A-N (hereinaftercollectively and/or generically referred to as “data packets 304”). Oneor more of the data packets 304 can include a header 306 and a payload308, which can include the content of the data packet 304.

In some embodiments, the deep packet inspection function 142 can beconfigured to allow the traffic 300 to pass through the deep packetinspection function 142 without any other operations or activities. Insome other embodiments, the deep packet inspection function 142 canperform various operations or activities on the traffic 300, as will beexplained below, and allow the traffic 300 to exit the deep packetinspection function 142. Regardless of whether or not other functions,operations, or activities are taken with respect to the traffic 300, thedeep packet inspection function 142 can allow the traffic 300 to exitthe deep packet inspection function 142 along an outbound traffic path310, which can correspond to a path along which outbound traffic flowsaway from the deep packet inspection function 142. Although not shownwith respect to other paths illustrated in FIG. 3, it should beunderstood that the traffic 300 can exit the deep packet inspectionfunction 142 as a stream or set of data packets 304 as illustrated withrespect to the traffic 300 arriving at the deep packet inspectionfunction 142. It should be understood that this example is illustrativeand therefore should not be construed as being limiting in any way.

As noted above, the deep packet inspection function 142 can completevarious functions, operations, or activities with respect to the traffic300. In particular, the deep packet inspection function 142 can create afork in the traffic 300. In particular, the deep packet inspectionfunction 142 can replicate the inbound traffic 300 to obtain a copy ofthe traffic 300 in addition to the original traffic 300. One of theoriginal traffic 300 or the copy of the traffic 300 can be routed out ofthe deep packet inspection function 142 along the outbound traffic path310, while the other of the original traffic 300 or the copy of thetraffic 300 can be routed out of the deep packet inspection function 142along the forked traffic path 312.

In some other embodiments, the deep packet inspection function 142 canbe configured to block the traffic 300. If the deep packet inspectionfunction determines that traffic 300 is to be blocked, the traffic 300can be returned to a source of the traffic 300, deleted, or otherwiseimpeded from proceeding through the deep packet inspection function 142.In FIG. 3, the traffic 300 is shown being returned to a sender along ablocked traffic path 314. It should be understood that this example isillustrative and therefore should not be construed as being limiting inany way.

In some other embodiments, the deep packet inspection function 142 canbe configured to reshape the traffic 300 before allowing the traffic 300to exit the deep packet inspection function 142. If the deep packetinspection function determines that traffic 300 is to be reshaped, thetraffic 300 can be reshaped and routed out of the deep packet inspectionfunction 142 along the outbound traffic path 310 or the reshaped trafficpath 316. As used herein, “shaping” when used to refer to traffic 300,can include applying or affecting a quality of service attribute orparameter to or of the traffic 300 or affecting the flow of the traffic300 in some way, for example by delaying the traffic 300 and/or creatinggaps or pauses between packets 304 of the traffic 300. It should beunderstood that this example is illustrative and therefore should not beconstrued as being limiting in any way.

In some other embodiments, the deep packet inspection function 142 canbe configured to modify the traffic 300 before allowing the traffic 300to exit the deep packet inspection function 142. In some embodiments,for example, the deep packet inspection function 142 can modify headers306 of the traffic 300, payloads 308 of the traffic 300, or the like. Ifthe deep packet inspection function 142 determines that traffic 300 isto be modified, the traffic 300 can be modified and routed out of thedeep packet inspection function 142 along the outbound traffic path 310or the modified traffic path 318. It should be understood that thisexample is illustrative and therefore should not be construed as beinglimiting in any way.

In some embodiments, the deep packet inspection function 142 can beconfigured to report events to various entities. For example, the deeppacket inspection function 142 can create and/or distribute one or moreevents to various recipients along a reporting path 320. According tovarious embodiments, the events and/or reports can be transmitted tovarious recipients for alarming, analysis, logging, or other purposes.It should be understood that these examples are illustrative andtherefore should not be construed as being limiting in any way.

Turning now to FIG. 4, aspects of a method 400 for instantiating a deeppacket inspection function 142 will be described in detail, according toan illustrative embodiment. It should be understood that the operationsof the methods disclosed herein are not necessarily presented in anyparticular order and that performance of some or all of the operationsin an alternative order(s) is possible and is contemplated. Theoperations have been presented in the demonstrated order for ease ofdescription and illustration. Operations may be added, omitted, and/orperformed simultaneously, without departing from the scope of theconcepts and technologies disclosed herein.

It also should be understood that the methods disclosed herein can beended at any time and need not be performed in its entirety. Some or alloperations of the methods, and/or substantially equivalent operations,can be performed by execution of computer-readable instructions includedon a computer storage media, as defined herein. The term“computer-readable instructions,” and variants thereof, as used herein,is used expansively to include routines, applications, applicationmodules, program modules, programs, components, data structures,algorithms, and the like. Computer-readable instructions can beimplemented on various system configurations including single-processoror multiprocessor systems, minicomputers, mainframe computers, personalcomputers, hand-held computing devices, microprocessor-based,programmable consumer electronics, combinations thereof, and the like.

Thus, it should be appreciated that the logical operations describedherein are implemented (1) as a sequence of computer implemented acts orprogram modules running on a computing system and/or (2) asinterconnected machine logic circuits or circuit modules within thecomputing system. The implementation is a matter of choice dependent onthe performance and other requirements of the computing system.Accordingly, the logical operations described herein are referred tovariously as states, operations, structural devices, acts, or modules.These states, operations, structural devices, acts, and modules may beimplemented in software, in firmware, in special purpose digital logic,and any combination thereof. As used herein, the phrase “cause aprocessor to perform operations” and variants thereof is used to referto causing a processor of a computing system or device, such as thecontrol system 102 or the computer system 200, to perform one or moreoperations and/or causing the processor to direct other components ofthe computing system or device to perform one or more of the operations.

For purposes of illustrating and describing the concepts of the presentdisclosure, the methods disclosed herein are described as beingperformed by the control system 102 or the computer system 200 viaexecution of one or more software modules such as, for example, themodules illustrated and described in FIGS. 1-2 including, but notlimited to, the operations management controller 106, the infrastructurecontrol 112, the network control 118, the service control 122, and/orthe deep packet inspection function 142. It should be understood thatadditional and/or alternative devices and/or network nodes can providethe functionality described herein via execution of one or more modules,applications, and/or other software including, but not limited to, themodules shown in FIGS. 1-2. Furthermore, although the particular modulesare mentioned as being capable of providing the disclosed operations, itshould be understood that the illustrated embodiments are illustrative,and should not be viewed as being limiting in any way.

The method 400 begins at operation 402. At operation 402, the controlsystem 102 can detect a service request. The service request can includea request relating to a service 134. Thus, the service request cancorrespond to an order for a new service 134, a request to instantiate anew service 134, a request to scale a service 134, a request toterminate a service 134, or the like. It should be understood that thecontrol system 102 can detect the request in operation 402 or receivethe request. In the embodiment shown in FIG. 4, the service requestdetected in operation 402 can correspond to a request to create the newservice 134. In response to the service request (or detecting theservice request), the control system 102 can begin operations asillustrated and described herein. In some embodiments, the controlsystem 102 can perform operation 402 by executing the operationsmanagement controller 106 and/or functionality associated with theoperations management controller 106 as illustrated in FIG. 4. It shouldbe understood that this example is illustrative and therefore should notbe construed as being limiting in any way.

From operation 402, the method 400 proceeds to operation 404. Atoperation 404, the control system 102 can check one or more policies,recipes, and/or inventory to determine service elements to include in aservice 134 that is responsive to the service request detected inoperation 402. Thus, the control system 102 can determine or identifyone or more functions that the service 134 will provide and determine,based upon the determined or identified functions, one or more serviceelements. At operation 404, the control system 102 also can check one ormore policy rules to determine how a service 134 should be createdand/or various features, requirements, architecture, resources, and/oroperational framework associated with such a service 134.

According to various embodiments of the concepts and technologiesdescribed herein, operation 404 can include determining that a deeppacket inspection function 142 is to be created as part of the service134 and/or that a deep packet inspection function 142 is to be tied tothe service 134. In some embodiments, the control system 102 can performoperation 404 by executing the operations management controller 106and/or functionality associated with the operations managementcontroller 106 as illustrated in FIG. 4. It should be understood thatthis example is illustrative and therefore should not be construed asbeing limiting in any way.

From operation 404, the method 400 proceeds to operation 406. Atoperation 406, the control system 102 can identify an infrastructurecontrol function, a network control function, and/or a service controlfunction for the service 134 that is requested by way of the servicerequest received or detected in operation 402. According to variousembodiments of the concepts and technologies described herein, thecontrol system 102 can select an appropriate infrastructure controlfunction, network control function, and/or service control function fromany number of existing control functions to control the service 134and/or various service functions associated with the service 134.

In some other embodiments, the control system 102 may determine that theappropriate service control function does not exist and, in response tomaking such a determination, can create the service control functionthat will control the service 134. Thus, it should be understood that inaddition to designating or selecting an infrastructure control function,network control function, and a service control function, operation 406can include creating and/or allocating a service control function. Insome embodiments, the control system 102 can perform operation 406 byexecuting the operations management controller 106 and/or functionalityassociated with the operations management controller 106 as illustratedin FIG. 4. It should be understood that this example is illustrative andtherefore should not be construed as being limiting in any way.

From operation 406, the method 400 proceeds to operation 408. Atoperation 408, the control system 102 can instantiate and validate oneor more virtual machines associated with the service 134 and one or moredeep packet inspection functions 142. According to some embodiments, theservice 134 created by way of the method 400 can include an embedded orstandalone deep packet inspection function 142 as noted above. As such,the virtual machines instantiated in operation 408 can include anembedded or standalone deep packet inspection function 142 and/or one ormore components thereof such as a deep packet inspection virtual switch202 and/or a deep packet inspection virtual function 204 if requested orinstructed by an entity such as the operations management controller106.

According to various embodiments of the concepts and technologiesdescribed herein, the instantiation of the deep packet inspectionfunction 142 can be completed by one or more of the infrastructurecontrol 112, the network control 118, and/or the service control 122.Thus, while FIG. 4 shows the instantiation of the deep packet inspectionfunction 142 at the infrastructure control 112, it should be understoodthat this embodiment is one example and should not be construed as beinglimiting in any way. In particular, in some embodiments theinfrastructure control 112 can instantiate one or more virtual machinesand load images to the virtual machines where the images can includecomponents of the service 134 and components of the deep packetinspection function 142.

In some embodiments, a recipe for a service 134 and/or a deep packetinspection function 142 embedded in and/or associated with a service 134can specify where and how the components of the deep packet inspectionfunction 142 will be instantiated. Thus, in some embodiments the recipecan specify that the infrastructure control 112 will load the componentsof the deep packet inspection function 142 to the virtual machines asshown in FIG. 4. In some other embodiments, the recipe can specify thatthe network control 118 can establish the deep packet inspection virtualswitch 202 after allocation of resources by the infrastructure control112. In yet other embodiments, the service control 122 can load the deeppacket inspection virtual function 204 to the virtual machines or otherresources allocated by the infrastructure control 112. Thus, it shouldbe understood that the various components of the control system 102 caninstantiate and/or validate the components of the deep packet inspectionfunction 142.

According to various embodiments, an event can be reported to aninfrastructure DCAE process and/or the infrastructure inventory can beupdated as part of operation 408. Although not shown in FIG. 4, itshould be understood that the operations management controller 106module of the control system 102 can instruct the infrastructure control112, or a component thereof, to instantiate one or more virtualmachines. Thus, in some embodiments of the concepts and technologiesdescribed herein, where the components of the control system 102 can bedistributed across multiple devices, it should be understood thatcommunications between the components can occur to trigger one or moreof the operations illustrated and described herein. It should beunderstood that this example is illustrative and therefore should not beconstrued as being limiting in any way.

In some embodiments of the method 400, the virtual machines and/ormultiple virtual functions can be instantiated by the infrastructurecontrol 112 module of the control system 102, while one or more deeppacket inspection functions 142 and/or components thereof (e.g., a deeppacket inspection virtual switch 202 and/or a deep packet inspectionvirtual function 204) can be instantiated and/or configured by thenetwork control 118 and/or the service control 122 as mentioned above.As such, in some embodiments, the control system 102 can performoperation 408 by executing the operations management controller 106, theinfrastructure control 112, the network control 118, the service control122 and/or functionality associated with the operations managementcontroller 106, the infrastructure control 112, the network control 118,and/or the service control 122 as illustrated in FIG. 4. It should beunderstood that this example is illustrative and therefore should not beconstrued as being limiting in any way.

From operation 408, the method 400 proceeds to operation 410. Atoperation 410, the control system 102 can establish transport betweenthe virtual machines instantiated in operation 408 (and in someembodiments the deep packet inspection function 142 and/or componentsthereof instantiated and/or configured in operation 410) and update theinventory 110 and/or one or more local inventories. Thus, operation 410can include instructing the network control 118 to establish the deeppacket inspection virtual switch 202 and/or instructing the servicecontrol 122 to establish the deep packet inspection virtual function204. Additionally, operation 410 can include the network control 118creating transport or ensuring that transport exists between the networkcontrol 118 and the deep packet inspection virtual switch 204, as wellas creating transport or ensuring that transport exists between theservice control 122 and the deep packet inspection virtual function 204.In some embodiments, the control system 102 can perform operation 410 byexecuting the network control 118 and/or functionality associated withthe network control 118 as illustrated in FIG. 4. It should beunderstood that this example is illustrative and therefore should not beconstrued as being limiting in any way.

In some embodiments of the method 400, the method 400 can proceed fromoperation 410 to operation 412. In particular, in some embodiments ofthe method 400 in which the one or more deep packet inspection functions142 (and/or one or more deep packet inspection virtual functions 204associated therewith) were not configured at operation 408, the method400 can proceed from operation 410 to operation 412. In some otherembodiments of the method 400 in which the deep packet inspectionfunction 142 and/or components thereof such as the deep packetinspection virtual switch 202 and/or the deep packet inspection virtualfunction 204 have been configured, the method 400 can flow fromoperation 410 to operation 414.

At operation 412, the control system 102 can configure the deep packetinspection function 142 and/or one or more deep packet inspectionvirtual switches 202 or deep packet inspection virtual functions 204thereof, which may be instantiated in operation 408. As used herein withreference to operation 412, “configuring” the deep packet inspectionfunction 142 and/or components thereof can refer to activating the deeppacket inspection function 142 and/or establishing a base or defaultconfiguration for the deep packet inspection function 142. Thus,operation 412 can include specifying what application programminginterfaces the deep packet inspection function 142 will use, expose, oraccess, or the like.

It can be appreciated that if the deep packet inspection functions 142(and/or the deep packet inspection virtual switches 202 or the virtualfunctions 204 thereof) are instantiated and configured in operation 408,that operation 412 may be skipped or omitted. Thus, it can beappreciated that operation 412 may be performed by the control system102, in some embodiments, where the infrastructure control 112instantiates the deep packet inspection functions 142 (and/or the deeppacket inspection virtual switches 202 or the deep packet inspectionvirtual functions 204) in operation 408, though this is not necessarilythe case. In some embodiments, the control system 102 can performoperation 412 by executing the service control 122 and/or functionalityassociated with the service control 122 as illustrated in FIG. 4. Itshould be understood that this example is illustrative and thereforeshould not be construed as being limiting in any way.

From operations 410 or 412, the method 400 proceeds to operation 414. Atoperation 414, the control system 102 can establish transport betweenthe deep packet inspection function 142 and other services 134 withwhich the deep packet inspection function 142 is associated, to whichthe deep packet inspection function 142 is chained, from which the deeppacket inspection function 142 receives the traffic 300, to which thedeep packet inspection function 142 routes the traffic 300, combinationsthereof, or the like. It should be appreciated that in some embodimentsof the method 400 in which operation 412 is omitted, operations 410 and414 can be combined into a single operation. It should be understoodthat this example is illustrative and therefore should not be construedas being limiting in any way. In some embodiments, the control system102 can perform operation 414 by executing the network control 118and/or functionality associated with the network control 118 asillustrated in FIG. 4. It should be understood that this example isillustrative and therefore should not be construed as being limiting inany way.

From operation 414, the method 400 proceeds to operation 416. Atoperation 416, the control system 102 can validate the service 134end-to-end and update the inventory 110. In some embodiments, each ofthe scope domains can validate the service 134 or portion associatedwith that scope domain instead of the control system 102 providingend-to-end validation. In some embodiments in which the operationsmanagement controller 106 validates the service 134 end-to-end, thecontrol system 102 can perform operation 416 by executing the operationsmanagement controller 106 and/or functionality associated with theoperations management controller 106 as illustrated in FIG. 4. In someembodiments in which each of the scope domains validates a portion ofthe service 134, the control system 102 can perform operation 416 byexecuting the operations management controller 106, the infrastructurecontrol 112, the network control 118, and/or the service control 122and/or functionality associated with these modules. It should beunderstood that this example is illustrative and therefore should not beconstrued as being limiting in any way.

While the above description of the method 400 has describedinstantiation of the deep packet inspection function 142 and/orcomponents thereof, it should be understood that the deep packetinspection virtual functions 204 may be instantiated in the method 400and the deep packet inspection virtual switch 202 may be instantiatedand/or configured at other times, if desired. Thus, for example, thedeep packet inspection virtual function 204 can be instantiated and/orconfigured in the method 400 and the deep packet inspection virtualswitch 202 can be configured by the deep packet inspection virtualfunction 204 as will be illustrated and described in more detail hereinwith reference to FIGS. 7-8. It should be understood that these examplesare illustrative and therefore should not be construed as being limitingin any way.

From operation 416, the method 400 proceeds to operation 418. The method400 ends at operation 418.

Turning now to FIG. 5, aspects of a method 500 for scaling a deep packetinspection function 142 will be described in detail, according to anillustrative embodiment. The method 500 begins at operation 502. Atoperation 502, the control system 102 can detect (or receive) a servicerequest. According to various embodiments of the concepts andtechnologies described herein, the service request detected or receivedin operation 502 can correspond to a request to adjust or change acapacity associated with the service 134, or another type of servicerequest. In some embodiments, the control system 102 can performoperation 502 by executing the operations management controller 106and/or functionality associated with the operations managementcontroller 106 as illustrated in FIG. 5. It should be understood thatthis example is illustrative and therefore should not be construed asbeing limiting in any way.

From operation 502, the method 500 proceeds to operation 504. Atoperation 504, the control system 102 can instantiate and validate oneor more virtual machines associated with the service 134 and one or moredeep packet inspection functions 142. As explained above with referenceto FIG. 4, the images loaded and/or validated in operation 504 caninclude an embedded or standalone deep packet inspection function 142and/or one or more components thereof such as a deep packet inspectionvirtual switch 202 and/or a deep packet inspection virtual function 204.Thus, as explained above, the control system 102 can analyze therecipes, policies, or the like, to determine what virtual machinesand/or functions are to be created, updated, or the like, as well as todetermine what deep packet inspection functions 142 and/or componentsare to be created, updated, or the like.

According to various embodiments of the concepts and technologiesdescribed herein, the instantiation of the deep packet inspectionfunction 142 can be completed by one or more of the infrastructurecontrol 112, the network control 118, and/or the service control 122.Thus, while FIG. 5 shows the instantiation of the deep packet inspectionfunction 142 at the infrastructure control 112, it should be understoodthat this embodiment is one example and should not be construed as beinglimiting in any way. In particular, in some embodiments theinfrastructure control 112 can instantiate one or more virtual machinesand load images to the virtual machines where the images can includecomponents of the service 134 and components of the deep packetinspection function 142. Alternatively, the network control 118 and/orthe service control 122 can instantiate one or more components of thedeep packet inspection function 142.

In some embodiments, a recipe for a service 134 and/or a deep packetinspection function 142 embedded in and/or associated with a service 134can specify where and how the components of the deep packet inspectionfunction 142 will be instantiated. Thus, in some embodiments the recipecan specify that the infrastructure control 112 will load the componentsof the deep packet inspection function 142 to the virtual machines asshown in FIG. 5. In some other embodiments, the recipe can specify thatthe network control 118 can establish the deep packet inspection virtualswitch 202 after allocation of resources by the infrastructure control112. In yet other embodiments, the service control 122 can load the deeppacket inspection virtual function 204 to the virtual machines or otherresources allocated by the infrastructure control 112. Thus, it shouldbe understood that the various components of the control system 102 caninstantiate and/or validate the components of the deep packet inspectionfunction 142.

Although not shown in FIG. 5, it should be understood that theoperations management controller 106 module of the control system 102can instruct the infrastructure control 112, or a component thereof, toinstantiate one or more virtual machines. Thus, in some embodimentswhere the components of the control system 102 are distributed acrossmultiple devices, it should be understood that communications betweenthe components can occur to trigger one or more of the operationsillustrated and described herein. It should be understood that thisexample is illustrative and therefore should not be construed as beinglimiting in any way.

In some embodiments, the control system 102 can perform operation 504 byexecuting the operations management controller 106, the infrastructurecontrol 112, the network control 118, the service control 122, and/orfunctionality associated with the operations management controller 106,the infrastructure control 112, the network control 118, and/or theservice control 122. It should be understood that this example isillustrative and therefore should not be construed as being limiting inany way.

From operation 504, the method 500 proceeds to operation 506. Atoperation 506, the control system 102 can establish transport betweenthe virtual machines and/or respective functions instantiated inoperation 504 and update the inventory 110. Thus, in various embodimentsof the concepts and technologies described herein, operation 506 caninclude establishing transport between these and/or other functions andthe components of the deep packet inspection function 142 including, butnot limited to, the deep packet inspection virtual switch 202 and/or thedeep packet inspection virtual function 204, and/or one or more virtualmachines instantiated in operation. In some embodiments, the controlsystem 102 can update the inventory 110 and/or the local inventoriesassociated with the various components or modules of the control system102 to reflect creation and/or establishment of the transport inoperation 506. Additionally, operation 506 can include the networkcontrol 118 creating transport or ensuring that transport exists betweenthe network control 118 and the deep packet inspection virtual switch204, as well as creating transport or ensuring that transport existsbetween the service control 122 and the deep packet inspection virtualfunction 204. In some embodiments, the control system 102 can performoperation 506 by executing the network control 118 and/or functionalityassociated with the network control 118 as illustrated in FIG. 5. Itshould be understood that this example is illustrative and thereforeshould not be construed as being limiting in any way.

From operation 506, the method 500 proceeds to operation 508. Atoperation 508, the control system 102 can update network virtualfunctions and/or network infrastructure networking functions. In someembodiments, the control system 102 can perform operation 508 byexecuting the network control 118 and/or functionality associated withthe network control 118 as illustrated in FIG. 5. It should beunderstood that this example is illustrative and therefore should not beconstrued as being limiting in any way.

In some embodiments of the method 500, the method 500 can proceed fromoperation 508 to operation 510. In particular, in some embodiments ofthe method 500 in which the deep packet inspection function 142 and/orcomponents thereof such as the deep packet inspection virtual switch 202and the deep packet inspection virtual function 204 were not configuredat operation 508, the method 500 can proceed from operation 508 tooperation 510. In some other embodiments of the method 500 in which thedeep packet inspection function 142 and/or components thereof such asthe deep packet inspection virtual switch 202 and the deep packetinspection virtual function 204 have been configured, the method 500 canflow from operation 508 to operation 512.

At operation 510, the control system 102 can configure the deep packetinspection function 142 and/or components thereof such as the deeppacket inspection virtual switch 202 and the deep packet inspectionvirtual function 204. Configuring the deep packet inspection function142 and/or components thereof in operation 510 can include activatingthe deep packet inspection function 142 and/or establishing a base ordefault configuration for the deep packet inspection function 142. Thus,operation 510 can include specifying what application programminginterfaces the deep packet inspection function 142 will use, expose, oraccess, or the like. In some embodiments, the control system 102 canperform operation 510 by executing the service control 122 and/orfunctionality associated with the service control 122 as illustrated inFIG. 5. It should be understood that this example is illustrative andtherefore should not be construed as being limiting in any way.

From operations 508 or 510, the method 500 proceeds to operation 512. Atoperation 512, the control system 102 can establish transport betweenthe deep packet inspection function 142 and other services 134. Itshould be appreciated that in some embodiments of the method 500 inwhich operation 510 is omitted, operations 508 and 512 can be combinedinto a single operation. It should be understood that this example isillustrative and therefore should not be construed as being limiting inany way.

In some embodiments, the control system 102 can perform operation 512 byexecuting the network control 118 and/or functionality associated withthe network control 118 as illustrated in FIG. 5. It should beunderstood that this example is illustrative and therefore should not beconstrued as being limiting in any way.

From operation 512, the method 500 proceeds to either operation 514A or514B. At operations 514A and 514B, the control system 102 can validatethe service end-to-end and update the inventory 110. As explained above,controls or control functions associated with each of the scope domainscan validate a portion of the service 134 and/or components thereofassociated with the domains. In some embodiments, the control system 102can perform operation 514A by executing the operations managementcontroller 106 and/or functionality associated with the operationsmanagement controller 106 as illustrated in FIG. 5. In some embodiments,the control system 102 can perform operation 514B by executing theservice control 122 and/or functionality associated with the servicecontrol 122 as illustrated in FIG. 5. It should be understood that thisexample is illustrative and therefore should not be construed as beinglimiting in any way.

As explained above with reference to the method 400, it should beunderstood that the deep packet inspection virtual functions 204 may beinstantiated in the method 500 and that the deep packet inspectionvirtual switch 202 may be instantiated and/or configured at other timesand/or via execution of other methods and/or processes, if desired.Thus, the method 500 can be used to instantiate and/or configure thedeep packet inspection virtual function 204 and the deep packetinspection virtual switch 202 can be configured by the deep packetinspection virtual function 204 at other times as will be illustratedand described in more detail herein with reference to FIGS. 7-8. In someother embodiments, the deep packet inspection function 142 and/orcomponents thereof can be instantiated and/or configured by way of themethod 500. As such, the illustrated embodiment should be understood asbeing illustrative and therefore should not be construed as beinglimiting in any way.

From operations 514A or 514B, the method 500 proceeds to operation 516.The method 500 ends at operation 516.

Turning now to FIG. 6, aspects of a method 600 for configuring a deeppacket inspection function 142 will be described in detail, according toan illustrative embodiment. The method 600 begins at operation 602. Atoperation 602, the computer system 200 can receive deep packetinspection configuration data 206. Specifically, the deep packetinspection configuration data 206 can be received at a deep packetinspection virtual function 204 hosted on the computer system 200 via adeep packet inspection virtual switch 202 hosted on the computer system200.

As explained above, the deep packet inspection configuration data 206can include data that instructs the deep packet inspection virtualfunction 204 and/or other components of the deep packet inspectionfunction 142 regarding how deep packet inspection is to be completed bythe deep packet inspection function 142. Thus, the deep packetinspection configuration data 206 can include instructions forinspecting traffic 300, how to handle the traffic 300, actions to takein response to receiving and/or analyzing the traffic 300, combinationsthereof, and the like. The deep packet inspection configuration data 206also can define how the traffic 300 is handled during and/or after theanalysis of the deep packet inspection function 142.

From operation 602, the method 600 proceeds to operation 604. Atoperation 604, the computer system 200 can configure the deep packetinspection virtual function 204 based upon the deep packet inspectionconfiguration data 206 received in operation 602. According to variousembodiments, the deep packet inspection configuration data 206 candefine how the deep packet inspection function 142 is to perform thedeep packet inspection, how packets and/or other data flows are to behandled during or after the deep packet inspection, and/or variousactions and/or event reporting functions that can be completed during orafter the deep packet inspection, combinations thereof, or the like.

From operation 604, the method 600 proceeds to operation 606. Atoperation 606, the computer system 200 can generate SDN configurationdata 210. The computer system 200 can generate the SDN configurationdata 210 for forwarding to the network control 118 and/or a modulethereof, which can be hosted and/or executed by the computer system 200and/or the control system 102. The SDN configuration data 210 caninstruct the network control 118 regarding configuration of the deeppacket inspection virtual switch 202 and therefore can be generated bythe deep packet inspection virtual function 204 to configure the deeppacket inspection virtual switch 202 to take certain actions withoutinvolving the deep packet inspection virtual function 204. For example,the SDN configuration data 210 can be generated to instruct the deeppacket inspection virtual switch 202 to block traffic 300, to forktraffic 300, or the like.

From operation 606, the method 600 proceeds to operation 608. Atoperation 608, the computer system 200 can provide the SDN configurationdata 210 to a service control function associated with the servicecontrol 122 and the service control 122 and/or the service controlfunction can provide the SDN configuration data 210 to the networkcontrol 118 and/or a network control function associated with thenetwork control 118. In some embodiments, the SDN configuration data 210can be provided directly to the network control 118, while in some otherembodiments the SDN configuration data 210 can be provided to thenetwork control 118 via the service control 122. Thus, the deep packetinspection virtual function 204 can effectively provide SDNconfiguration data 210 to the deep packet inspection virtual switch 202via generating the SDN configuration data 210 and providing the SDNconfiguration data 210 to the network control 118 directly and/or viathe service control 122. The network control 118 can provide the SDNconfiguration data 210 to the deep packet inspection virtual switch 202,though not shown in FIG. 6.

From operation 608, the method 600 proceeds to operation 610. Atoperation 610, the computer system 200 and/or the control system 102 canconfigure the deep packet inspection virtual switch 202 based upon theSDN configuration data 210. In particular, the control system 102 and/orthe computer system 200 can configure the deep packet inspection virtualswitch 202 via execution of the network control 118 and/or other module.Thus, it can be appreciated that the deep packet inspection virtualswitch 202 can be configured using SDN technologies. It should beunderstood that this example is illustrative and therefore should not beconstrued as being limiting in any way.

From operation 610, the method 600 proceeds to operation 612. The method600 ends at operation 612.

Turning now to FIG. 7, aspects of a method 700 for using a deep packetinspection function 142 will be described in detail, according to anillustrative embodiment. The method 700 begins at operation 702. Atoperation 702, traffic 300 can arrive at the deep packet inspectionvirtual switch 202 hosted by the computer system 200. Thus, in operation702, the computer system 200 can, via execution of the deep packetinspection virtual switch 202, detect arrival of the traffic 300 at thedeep packet inspection virtual switch 202. Because the traffic 300 mayor may not be detected, and because the traffic 300 may arrive at thedeep packet inspection function 142 in additional and/or alternativeways, it should be understood that this example is illustrative andtherefore should not be construed as being limiting in any way.

From operation 702, the method 700 proceeds to operation 704. Atoperation 704, the computer system 200 can analyze the SDN configurationdata 210 to determine an action to take with respect to the traffic 300received (or detected) in operation 702. Thus, it can be appreciatedthat the SDN configuration data 210 can define rules or policies thatdefine how traffic 300 is handled based upon a source, destination, orroute associated with the traffic 300; based upon contents of thetraffic 300 (e.g., the payload 308 of one or more data packets 304 ofthe traffic 300); data in the routing tables 208; combinations thereof;or the like. It should be understood that the analysis illustrated inoperation 704 can be completed by the deep packet inspection virtualswitch 202, in some embodiments and therefore can occur at the networklayer instead of, or in addition to, the application or service layer.

From operation 704, the method 700 proceeds to operation 706. Atoperation 706, the computer system 200 can determine if the traffic 300should be blocked. The determination illustrated in operation 706 can bemade based upon the analysis illustrated in operation 704, if desired.If the computer system 200 determines, in operation 706, that thetraffic 300 should be blocked, the method 700 can proceed to operation708. At operation 708, the computer system 200 can block the traffic300. It can be appreciated with reference to FIG. 3 that he blockedtraffic 300 can be dropped, quarantined, and/or returned to a sender viathe blocked traffic path 314 shown in FIG. 3. Because the blockedtraffic 300 can be stored, disposed of in other ways, and/or subjectedto other operations, it should be understood that this example isillustrative and therefore should not be construed as being limiting inany way.

If the computer system 200 determines, in operation 706, that thetraffic 300 should not be blocked, the method 700 can proceed tooperation 710. At operation 710, the computer system 200 can determineif the traffic 300 should be routed to the deep packet inspectionvirtual function 204. Again, this determination can be based upon therouting tables 208 and/or information included in the SDN configurationdata 210 as well as information associated with the traffic 300. If thecomputer system 200 determines, in operation 710, that the traffic 300should not be routed to the deep packet inspection virtual function 204,the method 700 can proceed to operation 712.

At operation 712, the computer system 200 can determine if the traffic300 should be routed to another location. Thus, for example, thecomputer system 200 can determine that the traffic 300 should be routedto service 134, forked and routed to another location, copied and savedto a data storage device or location, routed to an alternativerecipient, or the like.

If the computer system 200 determines, in operation 712, that thetraffic 300 should be routed to another location, the method 700 canproceed to operation 714. At operation 714, the computer system 200 canmodify or insert one or more headers 306 into the traffic 300 and/ordata packets 304 included in the traffic 300. Thus, in operation 714,the computer system 200 can modify headers 306 associated with thetraffic 300 to effect routing of the traffic 300 to a determinedlocation such as a service 134, a data storage device, an alternativerecipient, or the like.

From operation 714, the method 700 can proceed to operation 716. Themethod 700 also can proceed to operation 716 from operation 712 if thecomputer system 200 determines, in operation 712, that the traffic 300should not be routed to another location. At operation 716, the computersystem 200 can route the traffic 300 to the destination or locationdetermined in operation 712. It can be appreciated that the computersystem 200 may not actively route the traffic 300 and that the computersystem 200 may instead output the traffic 300 for routing in accordancewith a header 306 or modified header 306. Because routing of the traffic300 can occur in a number of manners, various embodiments of routing thetraffic 300 will not be described in additional detail.

Returning now to operation 710, if the computer system 200 determinesthat the traffic 300 should be routed to the deep packet inspectionvirtual function 204, the method 700 can proceed to operation 718. Atoperation 718, the computer system 200 can modify and/or insert one ormore headers 306 (e.g., network headers) of one or more data packets 304included in the traffic 300 to effect routing of the traffic 300 to thedeep packet inspection virtual function 204. From operation 718, themethod 700 can proceed to operation 720.

At operation 720, the computer system 200 can analyze the traffic 300received in operation 702 and take an action with respect to the traffic300. The action taken in operation 720 can be based upon an analysis ofthe deep packet inspection configuration data 206. Additional details ofanalyzing the traffic 300 and the deep packet inspection configurationdata 206 and taking action based upon the analysis will be illustratedand described in more detail below with reference to FIG. 8. Briefly,the computer system 200 can analyze the traffic 300, analyze the deeppacket inspection configuration data 206, and take various actions basedupon the analysis including, but not limited to, creating events,modifying the traffic 300, storing the traffic 300, updating the deeppacket inspection virtual switch 202, modifying the SDN configurationdata 210, combinations thereof, or the like. Because additional and/oralternative actions can be taken with respect to the traffic 300, itshould be understood that these examples are illustrative and thereforeshould not be construed as being limiting in any way.

From operation 720, the method 700 proceeds to operation 716. Operation716 was described above. From operation 716, the method 700 can proceedto operation 722. The method 700 also can proceed to operation 722 fromoperation 708. The method 700 ends at operation 722.

Turning now to FIG. 8, aspects of a method 800 for analyzing traffic 300and taking action using a deep packet inspection function 142 will bedescribed in detail, according to an illustrative embodiment. It shouldbe understood that the operations of the method 800 can be, but are notnecessarily, executed by the computer system 200 at operation 720 of themethod 700 illustrated and described above with reference to FIG. 7.Because the operations of the method 800 can be performed at additionaland/or alternative times, it should be understood that this example isillustrative and therefore should not be construed as being limiting inany way.

The method 800 begins at operation 802. At operation 802, the computersystem 200 can analyze the deep packet inspection configuration data 206to determine an action to take with respect to the traffic 300. Inoperation 802, the computer system 200 can analyze the traffic 300received or detected in operation 702. In analyzing the traffic 300, thecomputer system 200 can analyze the traffic 300 (and/or data included inthe traffic 300) to identify a sender and a recipient, as well ascontents of the traffic 300. In some embodiments, the analysis of thetraffic 300 can begin with an analysis of the headers 306 associatedwith data packets 304 included in the traffic 300, though this is notnecessarily the case.

In some embodiments, the analysis can include analyzing the contents ofthe traffic 300 to determine what content is represented by the traffic300. It can be appreciated from FIG. 2 that the content can be analyzedby analyzing payloads 308 of one or more data packets 304 associatedwith and/or included in the traffic 300, though this is not necessarilythe case. Regardless of how the analysis is completed, the computersystem 200 can detect malware, viruses, or other malicious traffic 300,as well as other traffic 300 that may be desirable or undesirable forvarious reasons. For example, the computer system 200 can detect traffic300 associated with usage at peak times, types of traffic 300 that maybe associated with premium services, traffic 300 that may be associatedwith low cost services, low quality of service traffic 300, combinationsthereof, or the like). Thus, in operation 802, the computer system 200can determine contents of the traffic 300, recipients of the traffic300, senders of the traffic 300, other information, combinationsthereof, or the like.

Based upon the analysis of the deep packet inspection configuration data206 and the traffic 300, the computer system 200 can determine an actionto take with respect to the traffic 300. The action that is determinedcan be taken at the application or service layer or the network layer ofthe infrastructure 114. The action taken by the computer system 200 withrespect to the traffic 300 can include, but is not limited to, one ormore of the actions depicted in operations 804-810. Because otheractions can be taken, it should be understood that these examples areillustrative and therefore should not be construed as being limiting inany way.

From operation 802, the method 800 proceeds to operation 804. Atoperation 804, the computer system 200 optionally can update the SDNconfiguration data 210. Thus, in operation 804, the computer system 200can optionally create new or modified SDN configuration data 210 thatcan instruct the deep packet inspection virtual switch 202 to modifyhandling of certain types of traffic 300 based upon the analysisillustrated and described in FIGS. 7-8. By creating new or modified SDNconfiguration data 210, the result of the SDN configuration dataanalysis performed at operation 704 of the method 700 can be changed forsubsequent traffic 300 and therefore may not need to be routed to thedeep packet inspection virtual function 204 by the deep packetinspection virtual switch 202.

Although not separately shown in FIG. 8, the computer system 200 canalso output the new or modified SDN configuration data 210 and transmitthe new or modified SDN configuration data 210 to the network control118 for configuring the deep packet inspection virtual switch 202. Asexplained above, the SDN configuration data 210 can be provided directlyto the network control 118 in some embodiments and in some otherembodiments, the SDN configuration data 210 can be provided to thenetwork control 118 via the service control 122 and/or a componentthereof. The network control 118 can use the new or modified SDNconfiguration data 210 to configure the deep packet inspection virtualswitch 202, in some embodiments, as explained above. It should beunderstood that this example is illustrative and therefore should not beconstrued as being limiting in any way.

From operation 804, the method 800 proceeds to operation 806. Atoperation 806, the computer system 200 optionally can create an event orreport the traffic 300 to various entities. According to variousembodiments, the computer system 200 can create an event and transmitthe event through the deep packet inspection virtual switch 202. Theevents or reports can be routed to a DCAE process and/or to variousentities associated with the control system 102, if desired. Althoughnot separately shown in FIG. 8, the deep packet inspection virtualswitch 202 can perform another analysis on the SDN configuration data210 based upon receiving the event. Thus, it should be understood thatthe computer system 200 can again perform the functionality describedherein with reference to operation 704 upon receiving the event. Itshould be understood that this example is illustrative and thereforeshould not be construed as being limiting in any way.

From operation 806, the method 800 proceeds to operation 808. Atoperation 808, the computer system 200 optionally can modify the traffic300 and return the traffic 300 to the deep packet inspection virtualswitch 202. In modifying the traffic 300, the computer system 200 canmodify content or other information of the traffic 300, insert contentor information into the traffic 300, remove content or information fromthe traffic 300, combinations thereof, or the like. Thus, in operation808 the computer system 200 can modify the payload 308 of one or moredata packets 304 included in the traffic 300, modify one or more headers306 included in one or more data packets 304 included in the traffic300, combinations thereof, or the like. Because the traffic 300 can bemodified in additional and/or alternative ways, it should be understoodthat these examples are illustrative and therefore should not beconstrued as being limiting in any way.

From operation 808, the method 800 proceeds to operation 810. Atoperation 810, the computer system 200 optionally can replicate or forkthe traffic 300. In operation 810, the computer system 200 can create acopy of the traffic 300. The original traffic 300 can be allowed to passthrough the computer system 200 and the copy of the traffic 300 can beforked to another location, stored for future use, analyzed, or thelike. Because the traffic 300 can be forked in additional and/oralternative manners, it should be understood that this example isillustrative and therefore should not be construed as being limiting inany way.

From operation 810, the method 800 proceeds to operation 812. The method800 ends at operation 812.

Turning now to FIG. 9, additional details of the network 104 areillustrated, according to an illustrative embodiment. The network 104includes a cellular network 902, a packet data network 904, for example,the Internet, and a circuit switched network 906, for example, apublicly switched telephone network (“PSTN”). The cellular network 902includes various components such as, but not limited to, basetransceiver stations (“BTSs”), Node-B's or e-Node-B's, base stationcontrollers (“BSCs”), radio network controllers (“RNCs”), mobileswitching centers (“MSCs”), mobile management entities (“MMEs”), shortmessage service centers (“SMSCs”), multimedia messaging service centers(“MMSCs”), home location registers (“HLRs”), home subscriber servers(“HSSs”), visitor location registers (“VLRs”), charging platforms,billing platforms, voicemail platforms, GPRS core network components,location service nodes, an IP Multimedia Subsystem (“IMS”), and thelike.

A mobile communications device 908, such as, for example, a cellulartelephone, a user equipment, a mobile terminal, a PDA, a laptopcomputer, a handheld computer, and combinations thereof, can beoperatively connected to the cellular network 902. The cellular network902 can be configured as a 2G GSM network and can provide datacommunications via GPRS and/or EDGE. Additionally, or alternatively, thecellular network 902 can be configured as a 3G UMTS network and canprovide data communications via the HSPA protocol family, for example,HSDPA, EUL (also referred to as HSUPA), and HSPA+. The cellular network902 also is compatible with 4G mobile communications standards as wellas evolved and future mobile standards.

The packet data network 904 includes various devices, for example,servers, computers, databases, and other devices in communication withone another, as is generally known. The packet data network 904 devicesare accessible via one or more network links. The servers often storevarious files that are provided to a requesting device such as, forexample, a computer, a terminal, a smartphone, or the like. Typically,the requesting device includes software (a “browser”) for executing aweb page in a format readable by the browser or other software. Otherfiles and/or data may be accessible via “links” in the retrieved files,as is generally known. In some embodiments, the packet data network 904includes or is in communication with the Internet. The circuit switchednetwork 906 includes various hardware and software for providing circuitswitched communications. The circuit switched network 906 may include,or may be, what is often referred to as a plain old telephone system(POTS). The functionality of a circuit switched network 906 or othercircuit-switched network are generally known and will not be describedherein in detail.

The illustrated cellular network 902 is shown in communication with thepacket data network 904 and a circuit switched network 906, though itshould be appreciated that this is not necessarily the case. One or moreInternet-capable devices 910, for example, a PC, a laptop, a portabledevice, or another suitable device, can communicate with one or morecellular networks 902, and devices connected thereto, through the packetdata network 904. It also should be appreciated that theInternet-capable device 910 can communicate with the packet data network904 through the circuit switched network 906, the cellular network 902,and/or via other networks (not illustrated).

As illustrated, a communications device 912, for example, a telephone,facsimile machine, modem, computer, or the like, can be in communicationwith the circuit switched network 906, and therethrough to the packetdata network 904 and/or the cellular network 902. It should beappreciated that the communications device 912 can be anInternet-capable device, and can be substantially similar to theInternet-capable device 910. In the specification, the network 104 isused to refer broadly to any combination of the networks 902, 904, 906.It should be appreciated that substantially all of the functionalitydescribed with reference to the network 104 can be performed by thecellular network 902, the packet data network 904, and/or the circuitswitched network 906, alone or in combination with other networks,network elements, and the like.

FIG. 10 is a block diagram illustrating a computer system 1000configured to provide the functionality described herein for creatingand/or using a deep packet inspection virtual function such as the deeppacket inspection function 142, in accordance with various embodimentsof the concepts and technologies disclosed herein. The computer system1000 includes a processing unit 1002, a memory 1004, one or more userinterface devices 1006, one or more input/output (“I/O”) devices 1008,and one or more network devices 1010, each of which is operativelyconnected to a system bus 1012. The bus 1012 enables bi-directionalcommunication between the processing unit 1002, the memory 1004, theuser interface devices 1006, the I/O devices 1008, and the networkdevices 1010.

The processing unit 1002 may be a standard central processor thatperforms arithmetic and logical operations, a more specific purposeprogrammable logic controller (“PLC”), a programmable gate array, orother type of processor known to those skilled in the art and suitablefor controlling the operation of the server computer. As used herein,the word “processor” and/or the phrase “processing unit” when used withregard to any architecture or system can include multiple processors orprocessing units distributed across and/or operating in parallel in asingle machine or in multiple machines. Furthermore, processors and/orprocessing units can be used to support virtual processing environments.Processors and processing units also can include state machines,application-specific integrated circuits (“ASICs”), combinationsthereof, or the like. Because processors and/or processing units aregenerally known, the processors and processing units disclosed hereinwill not be described in further detail herein.
